Concord, Massachusetts.
Mass.
Concord. - to Concord late in the afternoon, rowing
very slowly against the wind and stream.
  Yesterday I heard Bobolinks at frequent intervals, 
most of them high in the air and, as I thought,
migrating. To-day I neither heard nor saw a
single bird.

  The Swifts also seem to have suddenly departed. At 
sunset last evening a dozen or more were circling
over the Mouse grounds but I saw only one
to-day.

  The Barn Robins still linger in small number but
I have seen no other species of the family this
month.

  A Black & White Aupin sang over this morn in some 
pines giving the warbling mid-summer song with
clearness and fervor.

  Crossing a field in Bedford  we started a large
flock of Chipping Sparrows and Bluebirds - fully thirty of
the former & perhaps half as many of the latter.
They flitted along ahead of us alighting on the posts
& rails of a fence & chasing one another after their
usual manner at this season.
  Just below Flint's Bridge many birds were perched on or
in the tops of tall maples whence they darted out after flies.
An Oriole, several Bluebirds, & Phoebes & many Chippies were thus engaged.
